Objects in Motion Reteach

Distance is

• A straight line length between the starting and stopping position of an object.

• The total path or length an object travels.

• How fast an object travels.

Displacement is

• A straight line length between the starting and stopping position of an object.

• The total path or length an object travels.

• How fast an object travels.
